Equipment

  • Large Skillet
  • Knife
  • Cutting Board
  • Measuring Spoons
  • Cookie sheet
  • Spatula or tongs

Ingredients
  

  • 1.5 tablespoons olive oil
  • 1 large red onion sliced into strips
  • 2 cloves garlic minced
  • 1 medium red bell pepper cut into strips
  • 1 pound beef sirloin tip steak cut into thin strips; grass-fed recommended
  • 4 ounces white mushrooms sliced
  • 2 teaspoons dried oregano
  • 1/2 teaspoon black pepper
  • salt to taste
  • 2 whole whole wheat pita pockets cut in half
  • 4 leaves romaine lettuce torn into small pieces
  • 1/4 cup Greek yogurt fat-free plain or fat-free sour cream (optional)

Instructions
 

  • Preheat the oven to 350°F (175°C).
  • Heat 1 tablespoon of the olive oil in a large skillet over medium-low heat.
  • Add the sliced mushrooms and sauté about 6 minutes until they release moisture and begin to brown.
  • Add the sliced red onion, minced garlic, and red bell pepper and continue sautéing about 4 minutes until the onion and pepper are tender.
  • Push the vegetables to the side and increase heat to medium; add the sirloin strips and cook 5–10 minutes, stirring occasionally, until no longer pink.
  • Season the mixture with dried oregano, black pepper, and salt to taste; stir well, cover, and simmer 5 minutes more. Drain any excess liquid.
  • Brush the remaining 1/2 tablespoon olive oil on both sides of the pita halves, place them on a cookie sheet, and warm in the oven 3–5 minutes.
  • Fill each warmed pita pocket with the meat-and-vegetable mixture, divide romaine lettuce among them, and top with a dollop of Greek yogurt or sour cream if using.

Notes

  • Use grass-fed sirloin for better flavor if available.
  • Greek yogurt is optional and can be omitted for a lighter sandwich.
  • Slice the steak thinly against the grain for tender bites.
